Two separate reports released this week offer a grim look at the state of air quality in North America. The continent already produces 6% of the world’s greenhouse gas (GHG) emissions from power plants, resulting in an array of health and environmental problems.

According to a joint report by the Environmental Integrity Project (EIP), EarthJustice, and the Sierra Club, the situation in America is getting worse. Their report rated the top 5 worst states for toxic power plant emissions. Some of the chemicals used to rank the states’ emission status included chromium, arsenic, lead, and mercury. These represent four of the most toxic heavy metals found in power plant emissions.

This report comes as the U.S.EPA is working on new standards for power plant emissions. The agency is under a court order to establish new emission standards, but action on air pollution standards has stalled, thanks to an attempt by the Republican-controlled Congress to strip the EPA of their court-granted authority to regulate air pollution.

The Inspector General of the Tennessee Valley Authority (TVA) released a new report showing that coal ash holding sites at several TVA-owned coal-fired power plants has managed to contaminate groundwater. The report says that chemical concentrations are so high in certain areas that they could pose a serious health risk to residents. Among the chemicals that the Inspector General’s report lists as being found in the water supply were arsenic, cadmium, beryllium, selenium, and vanadium.

While the chemicals found in the water supply show that there is a serious threat to local communities coming from the coal ash repositories, that isn’t the most disturbing part of the report. The real problem is that the TVA knew about the chemicals being leaked into the water supply for at least a decade, and did nothing. The report says that the TVA had found chemicals indicating coal ash leaks in areas in and around Memphis, as well as other sites across Tennessee.

The Environmental Integrity Project (EIP) has released a new report showing that coal ash disposal sites are threatening water supplies at 33 sites located in 19 different states across the U.S. The EIP says that the levels of heavy metals like arsenic in these locations are dangerously higher than federally accepted levels, which the group says could mean that legal action could be taken against the companies involved in the coal ash dumping.
